Harmoni Heating - Integration with ST

Hi - I’ve tried using the search, but annoyingly, typing Harmoni appears to fuzzy search Logitech Harmony

In short - I have a number of WiFi enabled heaters that utilise an app. They are not branded as ST or even Alexa enabled. They also do not use IR so I cannot utilise a blaster. However they are network enabled.

The app and details can be found here - https://www.harmoniheating.co.uk/products/harmoni-app

What is required to create a controller (if possible), is there someone willing to look into this for a fee or is it not that simple?
